Chūnibyō? A Mysterious Illness? Men in Gas Masks Feature

A gas mask with a slightly creepy and uncouth design with mecha-like characteristics gives the wearer an otherworldy impression. Originally, the gas mask was military supplies and used as a barrier to defend the airway against toxic gasses, but recently can be seen as props in survival games and Halloween costumes.
This time, we have an illustrated feature on “men in gas masks” with a punk and horror charm. Please take a look.
